Autoconf 2.50 released in 2001 made several macros obsolete including
the AC_TRY_RUN, AC_TRY_COMPILE and AC_TRY_LINK:
http://git.savannah.gnu.org/cgit/autoconf.git/tree/ChangeLog.2
These macros should be replaced with the current AC_FOO_IFELSE instead:
- AC_TRY_RUN with AC_RUN_IFELSE and AC_LANG_SOURCE
- AC_TRY_LINK with AC_LINK_IFELSE and AC_LANG_PROGRAM
- AC_TRY_COMPILE with AC_COMPILE_IFELSE and AC_LANG_PROGRAM
PHP 5.4 to 7.1 require Autoconf 2.59+ version, PHP 7.2 and above require
2.64+ version, and the PHP 7.2 phpize script requires 2.59+ version which
are all greater than above mentioned 2.50 version therefore systems
should be well supported by now.
This patch was created with the help of autoupdate script:
autoupdate <file>

The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.
In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.
This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
zval_dtor() doesn't make a lot of sense in PHP-7.* and it's used incorrectly in some places.
Its occurances should be replaced by zval_ptr_dtor() or zval_ptr_dtor_nogc(), or even more specialized destructors.
PHP requires integer typehints to be written "int" and does not
allow "integer" as an alias. This changes type error messages to
match the actual type name and avoids confusing messages like
"must be of the type integer, integer given".
E_RECOVERABLE errors are reported as "Catchable fatal error". This is
misleading, because they actually can't be caught via try-catch statements.
Therefore we change the wording to "Recoverable fatal error" as suggested by
Nikita.
This reverts commit 14d674442e.
I misread the discussion on the bug -- this is not the correct
fix. However the other proposed fix does not work either, so just
reverting for now.
